| To Roy. {Mr H. Royce - Buyer} from EFC. {E. Fowler Clarke - Electrical Engineer} X8796 EFC {E. Fowler Clarke - Electrical Engineer} 2/T14.9.27. WATFORD E06 MAGNETO NO.99158. This is the one magneto which we selected from the batch which you were having sent back, as the one which was reported to have completely failed to spark. We confirm this failure and our investigation leads us to the conclusion that the primary winding by some means or other is dead short-circuited. It is difficult to understand how this magneto was despatched in such a condition. We return the magneto herewith. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
